CARD-SHASPENING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 294,962, dated March 11, 1884.

Application filed December 20, 1883.

To all whom it may concern.-

Be it known that I, J OI-IN BRIERLEY, of Easthampton, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Gard-Sharpening Apparatus or Means, of which the following is a full, clear, and exact description.

My invention relates to that class of stricklers or card-sharpeners in which the strick= lers or sharpeners are mounted to reciprocate across the faces of the rotating cards and doffers; and the invention consists in the construction, arrangement, and combination of parts, as will be hereinafter described, and specifically set forth in the claims.

Reference is to be had to the accompanying drawings, forming part of'this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 represents a plan of a card-cylinder and doffer, frame carrying them, and means for rotating the same, with my improved devices for sharpening the cards applied; and Fig. 2, a vertical section of the same, taken transversely through the cylinder and doffer, with their frame shown only in part.

A A are the two sides of the frame, within which the card-cylinder Band doffer O, driven by belt band pulleys c c, are arranged to rotate. The wires or cards d d, as usual, do not wholly cover the bodies of said cylinder and doffer throughout their length, but leave bare or uncovered margins e e at the opposite ends thereof.

D D .are the flexible sharpeners or emerycloths, attached 011 their one edge to tubes f f, fitted to slide on and along rods 9 9, arranged over and parallel with the cylinder and doffer. These sharpeners, which may be made of leather faced with emery, rest on their otherwise unsupported portions upon the cards d d of the cylinder and doffer, and are of a width which is in excess of thewidth of the carded portions of the cylinder and doffer, or equal, say, to the width of the cards (I d and one of the bare marginal portions (2. Thus suspended and arranged, the sharpeners D D have a backward and forward traverse motion given to them equal in length, or thereabout, to the width of the one bare margin 6 at the (Model.)

ends of the cylinder and doffer-or, in other words, to the excess in width of the sharpeners relatively to the width of the cards on the revolving cylinder and dofferso that the whole of the wires will be covered by the sharpeners, and a uniform pressure and action will be had at all times over the whole width of the cards, to sharpen them without making them untrue by operating upon one portion of the cards more than another. These sharpeners are moved in a straight line or course across the faces of the cylinder and doffers by the straight guided motion of their carriers, and to this end the tubes f f may either be fitted to slide on the rods g g, as here shown, or said rods may have a sliding or traversing motion in their bearings, which are mounted on the sides A A of the frame or in standards thereon. The rod supporting the tube f over the doffer, is here shown as carried by standards *0 i on the sides A A, while the other rod, 9, supporting the tube f over the card-cylinder, has its bearings direct on the curved raised portions of said sides. v

To one of the sharpeners D is pivoted, at 7:, a lever, E, which extends to the other sharpener, where it passes loosely through an eye, Z. Motion imparted to-the free end of said lever E will cause the tubes and the sharpeners D, secured thereto, to reciprocate across the faces of the card and doifer. This motion may be imparted by hand, or by means of suitable mechanism operated from the carding-engine, or otherwise.

I am aware that a cross-bar having two centrally pivoted bars or arms has been mounted between the card and doffer of a carding-machine, said centrally-pivoted arms being loose- 1y secured to the stricklers extending across the face of said card and doffer cylinders, and said arms also being connected together by a rod caused to reciprocate by worm-gear and eccentric; and I do not desire to claim,broadly, such construction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The'combination, with the card and doffer cylinders 13 O, mounted to revolve in a suitable frame, of the sharpeners D D, secured to tubes f f, which are in turn mounted 011 4 transverse rods 9 1 secured to the frame above said cylinders 13 G, and a lever, E, pivoted to one sharpener, and loosely engaging the other sharpener by a suitable connection, whereby when motion is imparted to said lever the tubes and their sharpeners will be reciprocated, substantially as set forth.

2. The combination, with card and doli'er cylinders, of rods y secured to the frame above said cylinders, as shown, tubes f f, mounted on said rods, and carrying flexible sharpeners D D, of greater width than the toothed surfaces of said cylinders, the lever E, pivoted to one sharpener, D, and extend ing loosely through an eye, Z, on the other sharpener, whereby the sharpeners when reciprocated by said lever will at all times rest on the toothed surfaces of said cylinders, substantial] y as set forth.
